英文摘要在纯水介质中通过简单调节SrCO3浓度合成出了均一的橄榄状SrCO3粒子和由针状SrCO3粒子向两端辐射而成的束状聚集体.聚甲基丙烯酸钠(PMAA)的存在有着使SrCO3粒子形貌由束状聚集体逐渐变得两端钝化且膨胀的趋势,在适当条件下可得到较为均一的花生状、球状和树枝状SrCO3粒子.; The crystallization of SrCO3 particles from aqueous solutions in the absence and presence of a polyanionic additive has been investigated. Olive-like SrCO3 particles and bundle-like aggregates consisting of SrCO3 needles aligned radially toward both ends are synthesized in aqueous solutions by simply varying the SrCO3 concentration. Both ends of the bundle-like aggregates of SrCO3 needles tend to become rounded and extended in the presence of poly(methacrylic acid) (PMAA); accordingly, uniform peanut-like, spherical and dendritic SrCO3 particles can be prepared in suitable conditions, respectively.; 国家自然科学基金; 高等学校博士学科点专项科研项目; 教育部留学回国人员科研启动基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000180546100024&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 1; 126-128; 61
